The suggestion that the thread might be locked was based on the first few posts that did nothing but lament over the use of the term "suction". The forum is about aerodynamics and how it pertains to our model flying. Not about semantics of word usage. The issues of what word was used is no more pertinent to this forum than discussions about retractable landing gear or how to mix the correct shades of colour for WWII scale models. It was simply off topic for THIS forum. And that was why I suggested a new direction for the thread or closure. Not being nasty, just trying to keep the discussions for this forum area on topic.
